- Application filed June 10, 1908. Serial No. $87,732:

plied to it from a printing press or other suitable source.

Objects of the invention are to provide a folder which will receive the sheet, fold it neatly, rapidly and accurately while peru .itting freedom of movement of the sheet, so as to avoid all rubbing, creasing'or other undesirable action thereon; to avoid carrying the sheet about a cylinder, or cylindrical surface or between rolls during the folding operation, which is undesirable on account of offsetting, rubbing, smutting, creasing and otherwise injuring the product; toavoid also the unnecessary encumbering of the machine with a folding cylinder and its attendant mechanisms to provide simple, inexpensive, reliable and rapid mechanisms for taking, folding and delivering the sheets while leaving the sheet free except at the foldline where it is engaged by the folding devices; to provide for moving the sheet freely through the air while being folded and transmitted and at the same time delivering it in an advantageous position; to promote the uick dryingof the sheet by free movement though the air, and further to draw the arts of the sheet together after engagement by the folding jaws by the action of the atmosphere instead of by pressing between rolls, cylinders or tapes; to provide for ready view and observation of the mechanisms at all times and also easy access thereto; to

provide a mechanism realizing the various objects of invention which is simple and convenient in design and efiicient and reliable in operation. These and other objects of invention will in part be obvious and will in part appear more fully herein.

The invention consists in the novel parts, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and forming a part hereof, illustrate one embodiment of the invention, the same and 7 and extending thorobetween.

serving in connection with the description herein to explain the principles of the invention.

Of the drawings: Figure 1 is an elevation of a machine constructed in part in accordance with the principles of the invention; Fig. 2 is an end elevation corresponding to Fig. 1; Fig. 3 is an enlarged elevation ofv the folding mechanism; Fig. 4 is a left end elevation referred to Fig. 3; Fig. 5 is a central section, looking to right on Fig. 3; Fig. 6 is a right end elevation, referred to Fig. 8, with certain. parts omitted for clearness; Fig. 7 is a view corresponding generally to Fig. 5 showing the parts in a different pOSltlOIl and cooperating with the sheet-receiving means;

Fig. 8 is a detail of the folding jaws; and

Figs. 9 to 12 inclusive are details showing the operation of the folding and'delivering devices.

- Referring to the accompanying drawings, showing by way of example one embodiment of the invention, 1 indicates a traveling carrier having folding jaws 2 mounted thereon. The carrier 1 is shown arranged to swing about a center and as comprising a pair of arms 8 and 4, respectively, fixed to a suitable shaft 5. The shaft 5 is rotated from a source of power by suitable connections, such connections being omitted from the drawings as Well as those for other driven parts for the sake of clearness, the particular form of such connections constituting no part of the pres ent invention and being within the skill of ordinary mechanical designers. The folding jaws 2 are movably mounted upon the carrier 1 and are further shown herein as being rotatably mounted upon said carrier. Said jaws are further shown as being eccentrically mounted and having a motion of rotation about their eccentric bearings. Accordingly there are shown journals-d upon the arms 3 and 4, respectively, away from the shaft 5 and preferably near the ends of said arms, crank arms 6 and 7. Said crank arms are mounted for rotation with respect to the arms 3 and 4, the particular form of means for effecting such movement employed herein being described herciimfterf The folding jaws have, of course, movement relatively to each other and in this embodiment one folding jaw 9 is shown fixed to the crank arms 6 Fixed also to said crank arms and extending there between is a shaft 8 and the second folding jaw 10'-is rovided with lu s which the s aft 8 passes so t at the 'aw 10 may swin or oscillate upon the s aft 8 toward and from the jaw 9 to close upon and release thesheet.

Suitable means for opening and closing the folding jaws at the proper times and in proper relation to the other mechanisms are provided and in this embodiment I have chosen to em l'oy spring-pressed means for normally holding the folding jaws closed and also -to employ positive means for opening said 'aws to receive and release the sheet. The orm of such means herein shown comprises an arm 12 fixed relatively to the 'aw 10. Pivoted to the arm 12 is shown a ro 13 passing through an aperture in a lug 14-upon the arm 4. Spring pressure is a plied to the rod 13 to maintain the jaw 10 in t e, closed po-- sition and in this embodiment this is effected by a s iral spring 15 mounted upon the rod 13 an working between the lug 14 and a nut 16 threaded ulpon .therod 13 and which also serves to regu ate the amount of pressure.

As before indicated, suitable means for moving the folding jaws with referenoeto their carrier is provided, and the form there of herein shown comprises a fixed gear 17 mounted upon the frame 18 of the machine and a gear 19 fixed to and concentric with the crank arm 7'. A suitable intermediate 20 is shown mounted upon the arm 4. It

will thus be seen that as the arms 3 and 4 of the carrier travel with their shaft that the folding jaws travel or rotate with respect to In the drawings herewith the gears .17 and 19 are in the ratio of two to one and a more detailed description of their movement and working will be given later herein;

Suitable means for moving the foldin jaw 10 against its spring are rovided an the particular form thereof erein shown comprises a lever arm 21 connected to the jaw 10 at one end thereof and provided with a" suitable truck or anti-friction roll 22. The arm 12 is also utilized for this pur ose and is shown provided with a truck roi 23. Mounted upon an arm 24, fixed to a shaft 25 suitably 'ournaled in the carrier arm 3, is a cam s ape 26. Said camshap'e is movable so as to' pass into and out of. the path of the arm 21 with its truck roll 22 thereby to control the opening and closing movement of the jaw 10. Suitable devices are provided for giving the requisite movement at the pro er times to this cam shape 26 and in the i ustrated form thereof it is held out of the path of the roll 22 b spring pressure and moved into said path by positive means. The shaft 25 is accordingly shown mounted in a suitable bushing in the arm 3 and passin therethrough; Upon the opposite side of t e arm 3 is shown a lever 27 fixed t9 llle shaft 25. Pivoted to one scene? 11 through I end of the lever 27 is shown a rod 28 the free end of which asses through a lug 29 u on the arm 3. T readed upon the end of t e rod 28 is shown a nut 30 and bearing upon the opposite side of the lug 29 a spiral s ring 31 is coiled about said rod and bears a so upon a collar 32 carried on the rod. Mounted at the other end of the lever 27 is shown a truck roll 33. A suitably shaped cam 34 for engaging the roll 33 and thus movin the lever 27 and cam shape 26 as hereinbetore described is provided. This cam is shown mounted in proper position upon the machine frame.

The mechanism just described serves to 0 en the folding aws in one position, namely t e delivery position as will hereinafter appear more fully, and suitable devices are a so provided .for opening the jaws at the receiving position. According y there is shown a cam shape 35 mounted on an arm 36 fixed to a shaft-37 mounted in the arm 4. Fixed to the shaft 37 upon the opposite side of the arm 4 is shown a lever 38 and pivoted to one end thereof a rod 39 working m a lo I 41 is s own about the rod 39; and working 40 upon the arm 4. A spiral spring between the lug 40 and a collar 42 upon said rod. A nut 43 is provided at the end of the rod 39. At the other end of the lever 38 is shown a truck roll 44 and suitably located with reference thereto a cam 45, mounted upon the machine frame 18.

While certain features of the invention contemlate generally a traveling carrier and fo ding jaws movable thereon, other features of. the invention have in view proviiin a carrier traveling in an endless path and folding jaws mounted on the carrier and also traveling in an endless path. Other features of the invention in connection with the present embodiment will ap ear from the description and the ciaims.

uitable means for supplying sheets and also means for co'operatin with the folding jaws to fold the sheets tnere'into are pro vided and in the illustrated form thereof a traveling carrier 46 which may, if desired be in the form of a cylinder is provided carrying a suitable folding blade 47. In this embodiment also .the folding blade" 47 is shown fixed relatively to its carrier. Sheetsrnay be supplied in anysuitahle manner and for convenience they are shown herein as fed to the cylinder 46 at 48 in any suitable way and as being taken by grippers 49 and released therefrom as they are folded into the folding jaws.

Suitable devices for receiving the sheets from the folding jaws may be provided and according to certain features of the invention movable means 'for so receiving the sheets while moving in the same direction with the folding jaws or their carrier are contemplated and in the illustrated form thereof a cylinder ation.

drawings.

I 50 ieshown provided with grippers 51 which timed to approach the cylinder 46 so that the a folding jaws will meet the folding blade 47 to have the sheet upon the cylinder 46 folded theremto. As the jaws and blade so approadit. the truck roll 44 rides upon the cam as shown in Fig. 6 of the drawings. The card shape 35 swings inwardly, as shown in said ure,- and as the folding jaws rotate upon t e carrier arms the truck roll 23 rides upon said cam and is moved against'the ring 15 to swing the jaw 10 away-from the ed jaw 9. The foldin jaws are now in line with respect to the fixed folding blade 47,-substantially as shown in Fig. 9, and as the rotation of the carrier 1 and cylinder 16 rogresses the folding blade and the open olding jaws ap roach each other so that the sheetis tucked etween the jaws. The rotation of the jaws upon their carrier serves to keep them in alinement with the blade 47 so as to remain in favorable position with re spect thereto during the entire folding oper- The relative movements of the folding jaws and blade are substantially similar to those illustrated in Figs. 10 and 11 of the Pi 10 shows the sheet tucked into the jaws by the blade and Fig. 11 the sheet carried away by the folding jaws as the carrier 1 moves onward in its path. It will be understood of course that as the truck roll 44 passes off the cam 45, the spring 15 acts to close the jaws.

As hereinbefore stated the gears 17 and 19 are in the ratio of two to one thus giving one absolute rotation of the folding jaws for each rotation of the carrier but giving two rotations of the folding jaws relatively to the carrier for each rotation of the carrier. The

various positions of the folding jawsbetween line in Fig. 1 of the drawings.

the receiving and delivering positions for the sheet are approximately shown in dotted As the carrier 1 moves away from the receiving point for thesheet the folding jaws rotate inwardly relativje ly thereto to the position (a) the sheet swinging freely except along the fold where it 1 is engaged by the folding jaws and swinging inwardly between the arms 3 and 4 and also inwardly with res ect to the path of travel of the carrier. By t is movement the action'of the atmosphere tends to draw the two parts i of the sheet on the op osite side of the fold generally towards eac other without any rubbing or mechanical handling thereof whatsoever and Without bringing the surfaces into contact with a cylinder or any other mechanism. At the same time a slight layer or cushionof air is left between the two surfaces of the sheet which approach each other and while of very small thickness it serves to prevent smutting or offset of the inside faces and at the same time allows the drying action to go on. As the carrier 1 travels farther along its path to the position (b) the sheet is new swung outwardly by the rotation of the jaws and as the carrier moves onward to the position (0) the motion of the jaws permits the sheet to travel behind with the folded edge in front and still moving freely through the atmosphere exce t where engaged at the fold and it is then de ivered to the receiving cylinder 50, the grip are 51 en gaging it on the folded edge. uring this entire movement and this relatively long path of travel the sheet has-been subjected to the action of the air and of the air currents to facilitate and eX edite the drying thereof, While it has been olded together in the manner and with the advantages set forth. As the carrier 1 approaches the delivery position the truck roll 33 rides upon the cam 34 and moving the lever 27 against its spring 31 the truck roll 22 to swing the jaw 10 0 en in a manner which will be well un erstood from the foregoing description, the spring 31 serving to close the jaw as the roll 33 rides clear of its cam.

grippers 9 and '10 to take the sheet there'- from, if desired, in the manner shown in Fig.

7 of the drawings.

The described embodiment, it will be seen, permits the sheet to move free of the parts of the machine except along the fold where it is engaged by the folding jaws, that is, not necessarily free from accidental contact with some part of the machine as the sheet moves freely, but free from constraint or close contact with the parts of the machine whereby the sheet is bent, creased, smutte'd or otherwise more or less injured.

The handling of a newly printed sheet during the folding thereof in the manner herein described possesses great advantages, as will The grippers 5 1' may be arranged to work through slots in the be readily understood by anyone. skilled in the art and such advantages are especially apparent where it is desired to do high class printing and folding with great rapidity and without damage to or deterioration of the product. Such handling and its attendant advantages have been made possible for the first time by the present invention. It will be understood therefore that a machine has been provided which realizes the objects of invention and the advantages herein forth, together with other objects and advantages.

The invention, in its broader aspects, is not limited to the particular constructions shown, nor to any particular constructions by which it has been or may be carried into e feet, as many changes may be made in the construction without departing from the main principles of the invention and without sacrificing its chief advantages.
